[Cmake] ADD_DEFINITION to a specific target

[Andy Cedilnik]

Hi Marc,

Unfortunately it is a lot of work.

This is what you do. Create two subdirectories MyLib and MyLib_FOO. In
them set sources to be a list of sources with paths specified from
toplevel project directory:

PROJECT(foo)

then you do in MyLib:

ADD_LIBRARY(MyLib ${foo_SOURCE_DIR}/src/fic1.cxx
${foo_SOURCE_DIR}/src/fic2.cxx)

and in MyLib_FOO:

ADD_LIBRARY(MyLib_FOO ${foo_SOURCE_DIR}/src/fic1.cxx
${foo_SOURCE_DIR}/src/fic2.cxx)

While sources are still in the same directory ${foo_SOURCE_DIR}/src.

This will create separate object files and everything. Then you just put
whatever library specific things you want.
