[CMake] Resetting CMAKE_Fortran_FLAGS for a specific file

[Petr Kmoch]

Hi Marco.

Sane compilers allow later command-line options to override earlier ones,
so what you're doing should be fine. Unfortunately, I know some Fortran
compilers are not sane in this regard.

If you really need to solve this by explicitly modifying the global list
for a particular file, the only thing I can think of is move those files to
a separate CMakeList and turn them into an object library:

# In normal CMakeList:

add_subdirectory(special_file_dir)

add_executable(YourNormalTarget normal_file1.f90 normal_file2.f90
$<TARGET_OBJECTS:special_files>)


# In special_file_dir/CMakeLists.txt:

set(CMAKE_Fortran_FLAGS "-only -flags -you -want")

add_library(special_files OBJECT special_fil1.f90 special_file2.f90)


I haven't tested it, but it should work.

Petr
