Trouble building DLLs for VS2019

[mfellows]

I have a project that depends on a few libraries that are mainly built using vcpkg (i.e. vcpkg install boost:x64-windows), which by default work with Release mode and the -MD flag, but I've been struggling to get coinbrew to give me a compatible build - by default it seems to build static Debug (-MTd) libs which eventually throw a linker error when I try to build the project that depends on everything.

I've tried adding the --enable-shared flag to the coinbrew command line by itself, and also with ADD_CXXFLAGS="-MD -LD", but it seems to only change the file size of the resulting libs without building a corresponding set of dlls.

It must be user error, but I'm out of things to try - any help would be much appreciated! basically just trying to get "plain old" Release-mode dlls that play nice with other libraries built with vcpkg.

Using Windows 10, Msys2, and VS2019, following these steps:

• install msys2
• install the Intel oneAPI base toolkit + HPC toolkit (Fortran compiler and MKL)
• at the command prompt:
  set PATH=C:\development\msys64\usr\bin;%PATH%
  "C:\Program Files (x86)\Intel\oneAPI\setvars.bat"
  c:\development\msys64\usr\bin\bash.exe
  pacman -S make wget tar patch pkg-config diffutils dos2unix git svn
  mkdir /coin-or
  cd /coin-or
  wget https://raw.githubusercontent.com/coin-or/coinbrew/master/coinbrew
  chmod a+x ./coinbrew
  ./coinbrew fetch Cbc --latest-release --no-prompt
  ./coinbrew build Cbc ADD_CXXFLAGS="-MD -LD" --enable-shared --parallel-jobs=4 --enable-msvc --no-prompt --build=x86_64-w64-mingw32 --tests=none --prefix=/c/Development/lib/Cbc

--enable-msvc=MD should be what you need. My apologies if that's not mentioned in the documentation anywhere!
