|
|
# find_openmp (module)

|
|
# module Name of the module to which OpenMP libraries

|
# etc. should be added, e.g. "opm-core".

|
|
# Note: Compiler flags are always added globally, to avoid ABI
|
|
# incompatibility problems.

# Example:
|
|
# find_openmp (opm-core)
|
|
# remove_dup_deps (opm-core)
