project(tilp_and_gfm C)

###############################################
# Experimental CMake support for tilp and gfm #
###############################################
#
# This aims to provide a much simpler way to build and install tilp and gfm
# on computers that have decent and recent OS and toolchains.
# As a bonus, it provides better support for CMake-oriented IDE (e.g. CLion).
#
# Features:
#   - builds and installs both executables
#   - creates and installs i18n .mo files (when libs/tools are present)
#
# Caveats:
#   - you'll need to generate the pot files first (intltool-update --pot)
#   - not all the autotools/configure options are available
#   - probably doesn't work very well with ancient toolchains or on uncommon OSes
#
# In the future...:
#   - TODO: look at CPack features for bundling/packaging
#   - WISH: do not hardcode the (auto-generated...) potfiles_* target names
#   - WISH: add support for Windows (that will probably be annoying)
#
