[CMake] Project initialization file path

[Aby Louw]

Hi,


I have a Linux project that reads an initialization file on startup to
get some file names and variables.

When doing an in-source or out of source build, I generate the
initialization file in the CMAKE_BINARY_DIR and then also generate the C
file that reads this file so that I know the correct path.

Now when doing a "make install" I want to install the initialization
file on the /etc path. Therefore the initialization file path in the C
file needs to be updated. However I do not know how to recompile the C
target before installation happens.

I need something like a pre install or, add_dependency to install
target, but as far as I know this is not possible. Does anybody know of
a workaround to this problem?

regards,
Aby
