How do I build this again?

[anko]

I can recall having managed it in the past.

Following the current building instructions, I downloaded the correct CEF distribution files for my system, cd'd into a temp directory, then ran this command I constructed based on the instructions:

cmake -G "Ninja" -DCMAKE_BUILD_TYPE=Release \
    -DCEF_ROOT=~/dl/cef_binary_3.3282.1726.gc8368c8_linux64/Release \
    ~/src/cef-pdf

It failed for me with this:

CMake Error at CMakeLists.txt:192 (find_package):
  By not providing "FindCEF.cmake" in CMAKE_MODULE_PATH this project has
  asked CMake to find a package configuration file provided by "CEF", but
  CMake did not find one.

  Could not find a package configuration file provided by "CEF" with any of
  the following names:

    CEFConfig.cmake
    cef-config.cmake

  Add the installation prefix of "CEF" to CMAKE_PREFIX_PATH or set "CEF_DIR"
  to a directory containing one of the above files.  If "CEF" provides a
  separate development package or SDK, be sure it has been installed.


-- Configuring incomplete, errors occurred!

This is the first time I touch cmake, so I'm probably just dumb. What did I do wrong?

Relatedly, could the build be adapted to only 1 step? It would help automate testing and packaging.

nice to see you again : ) i'll have a look at this on monday morning and get back to you!

@anko: I get this error message if I use spotify "CEF source" instead of "Minimal Distribution" as /path/to/cef/release.

as the readme says:

cmake -G "Ninja" -DCMAKE_BUILD_TYPE=Release -DCEF_ROOT=/path/to/cef/release /path/to/cef-pdf
ninja 

/path/to/cef/release is the extracted "Minimal Distribution", /path/to/cef-pdf is the local path to the git repository.

Here an example command-line that worked for me:

cmake -G "Visual Studio 15 2017" -DCMAKE_BUILD_TYPE=Release -DCEF_ROOT="C:/Users/MyUser/Documents/Visual Studio 2017/CEF/cef_binary_3.3626.1895.g7001d56_windows32_minimal" "C:/Users/MyUser/Documents/Visual Studio 2017/Projects/cef-pdf"

Note:
You need to use forward-slash as directory-separator on Windows, otherwise you get something like

Invalid escape sequence \U
Invalid escape sequence \S

On Linux, you can use

cmake -G "Ninja" -DCMAKE_BUILD_TYPE=Release -DCEF_ROOT=/path/to/cef/release /path/to/cef-pdf
ninja

and actually, you don't need "Ninja", you can just use plain old unix makefiles:
cmake -G "Unix Makefiles" -DCMAKE_BUILD_TYPE=Release -DCEF_ROOT=/home/username/Desktop/src/cef_binary_3.3626.1895.g7001d56_linux64_minimal /home/username/Desktop/src/cef-pdf

Cmake on Linux is a bit of a bitch. When you run cmake --version, you might get

cmake: /usr/local/lib/libcurl.so.4: no version information available (required by cmake)

If you get that, you need to delete the symlink to libcurl.so.4, and create a new one

sudo rm /usr/local/lib/libcurl.so.4
sudo ln -s /usr/lib/x86_64-linux-gnu/libcurl.so.4.4.0 /usr/local/lib/libcurl.so.4

You might then get

CMake Error at CMakeLists.txt:49 (list):
list does not recognize sub-command FILTER

Which is to be expected, as list(FILTER) was introduced in CMake 3.6, and if you have a cmake version < 3.6, such as 3.5.1 on ubuntu 16.04, then using filter can't work.

You then need to apt-get --purge cmake, and subsequently install the latest version from cmake.org

wget https://cmake.org/files/v3.14/cmake-3.14.0-rc4-Linux-x86_64.sh
sudo sh cmake-3.14.0-rc4-Linux-x86_64.sh --prefix=/usr/local --exclude-subdir

Also, make might then treat warnings as erros.
So in the makefiles created by cmake, search for all files named flags.make, and remove -Werr, which treats warnings as errors (and because since some methods aren't being used, this creates a warning, and the with the -Werr option on, warnings will cause the build to build to fail (-Werr: treat warnings as errors).

The way cmake works, is you open a command prompt in the directory where you want to build in.
Then you issue the cmake command, cmake -G "Ninja" -DCMAKE_BUILD_TYPE=Release -DCEF_ROOT=/path/to/cef/release /path/to/cef-pdf, which generates the build files you need to compile the application. -G specifies the build target, can be Ninja, unix-makefiles, Visual-Studio solutions. Enter a bogus-name there, and cmake will list you the possible options for your machine.

You then use the makefiles or the Visual Studio solution to compile the project.
Note: Visual Studio on a 64-Bit processor wants to link against the 32-Bit dlls BY DEFAULT, so use the CEF minimal distribution for Win32 when you create the visual-studio solution with cmake...

You also need to switch the build to "Release", because in "Debug", the build will fail because of missing CEF files.
