Building project involving cmake, how do I make it aware of libraries

Question

When I try to build this project with cmake and gcc on a 64-bit linux (debian) machine, I get an error from the linker:

Linking C executable ../../../../cpsadams         


        

Answer 1

As this question is showing up on google and both answers won't point to the correct solution here it is:

In your CMakeLists.txt add ${CMAKE_DL_LIBS} to link against idl. It should look similar to this:

target_link_libraries(ExpandableTest
    ${CMAKE_DL_LIBS}
    Expandable
    ExpandableTestLibrary
)

Answer 2

Probably you need to add target_link_libraries() - see link text

Answer 3

Add this in CMakeLists.txt and it should work:

SET (CMAKE_CXX_FLAGS  "${CMAKE_CXX_FLAGS} -ldl")
