[CMake] Problem with generated source files and Fortran90 modules

[Petr Kmoch]

Hi Julien,

CMake correctly identifies that gen.90f depends on gen.f90.sh, but you
have no code to tell CMake that usegen.f90 depends on gen.f90. The
following should do the trick:

set_property(SOURCE usegen.f90 PROPERTY OBJECT_DEPENDS
"${CMAKE_BINARY_DIR}/gen.f90")
