I'm converting a large mixed C++/C cmake application to C++. The
project has many ".c" files that I would like to compile with the C++
compiler instead of the C compiler. Does anyone know the proper way
to do this in CMake?
Things I've tried:
1.) Changing CMAKE_C_COMPILER myself: Usually CMake doesn't let you
change CMAKE_C_COMPILER, but there are ways around that. This way
feels like a hack. The output while compiling still says "Compiling
C". In addition, forcing CMAKE_*_COMPILER to change makes it very
difficult to run plane cmake on Unix machines where curses is not
installed.
2.) Tell CMake that ".c" files are in the CXX language: I've tried
PROJECT(Blah CXX)
list(APPEND CMAKE_CXX_SOURCE_FILE_EXTENSIONS c)
When I run CMake on my project with these changes, I get errors like:
CMake Error: Cannot determine link language for target "foobar"
...for all my targets that depend only on .c files.
Help!
