Ninja with XL Fortran
When using the Ninja generator with XLF I get the following error:
CMake Error: Error required internal CMake variable not set, cmake may not be built correctly.
Missing variable is:
CMAKE_Fortran_PREPROCESS_SOURCE
CMake Error at
/path/to/cmake/CMakeTestFortranCompiler.cmake:30
(try_compile):
Failed to generate test project build system.
