hello,
My build step is not thread-safe (the instruction in the COMMAND part).
Every build step depends on one source file:
/add_custom_command(//
// DEPENDS on_source.file//
// OUTPUT//
// object_file_for_source_file//
// COMMAND not-thread-safe-compiler
I have an external CMake project that gets exported on install. The root
project uses it as a package. The external project must be installed
prior being used as a package.
I can solve this problem by using `ExternalProject` for both projects
and declare their dependency. My setup is different
s are expected to modify something
the external project’s build depends on in a way that is not
detectable via the step target dependencies (e.g. |SOURCE_DIR| is
used without a download method and developers might modify the
sources in |SOURCE_DIR|).
