So I tried:
find_library (M_LIB m)
target_link_libraries (pantheon-terminal ${M_LIB})
add_subdirectory (po)
add_executable (pantheon-terminal ${VALA_C})
You need to put the target_link_libraries under add_executable. With
add_executable, you define a new target, you can't use it before it is
defined.

But I get:
CMake Error at CMakeLists.txt:66 (target_link_libraries):
Cannot specify link libraries for target "pantheon-terminal" which
is not
built by this project.
Any ideas?

Just remember that link_libraries is deprecated, please use
target_link_libraries :P (well, I don't think it will be removed
from CMake before a lot of time, but it is useless to keep writing
code with it.)

Humm, if the fix was passing m, i guess cmake passes l prefix for us...
Nice!

Well Darcy, that email was @voldyman ;)
Regarding the general issue, I found a way to fix it, thanks to
devidfil's Github link, I just added:
link_libraries (m)
Right before the add_subdirectory call and it's working for everybody
now.
