I'm using a compiled library that I made, libexp.a. (Was compiled with PIC so its good for this use case).

I want to use it statically in my shared library and I can do that via Mixing static libraries and shared libraries.

So now I'm trying to get that working with CMake, my libexp.a is in the root directory and I do:

find_library(EXP NAMES exp PATHS ${PROJECT_SOURCE_DIR} NO_DEFAULT_PATH)

Then using it in target_link_libraries via ${EXP}, but during link time I still get a linking error of couldn't find -lexp. What is the right way to get this done? Using over 3.6

Why are you writing `$\{PROJECT_SOURCE_DIR}` instead of `${PROJECT_SOURCE_DIR}` as is normally done? – legalize Oct 16 '17 at 17:27
sorry, that was leftover, assume syntax is correct – Oct 16 '17 at 17:28
