cmake question

yfaye · 04-06-2009, 05:51 PM

I am trying to write a CMakeList.txt for a project (A). The project needs to use the library of another project (B). For gcc, using -L <path> -ldl works. How can I convert that into cmake file?

I tried include_directories, that doesn't seem to work

If it's not something external like SDL, OpenGL, or Boost, you can use TARGET_LINK_LIBRARIES. I can't really help you without details (like the CMakeLists.txt you've already written).

Can't log in to my work machine now. will post the CMakeLists.txt tomorrow.

If use TARGET_LINK_LIBRARIES, do I need to specific all the binaries or just including the dir name is fine?

For example, project B has a binary dir contating lib, bin, share... Each of the dir have multiple files. Can I just say

TARGET_LINK_LIBRARIES(A, /binary_path/B)?

Here are the links I suggested in your other post:

Here's an example from one of the links:

Quote:

# Make sure the compiler can find include files from our Hello library.
include_directories (${HELLO_SOURCE_DIR}/Hello)

# Make sure the linker can find the Hello library once it is built.
link_directories (${HELLO_BINARY_DIR}/Hello)

# Add executable called "helloDemo" that is built from the source files
# "demo.cxx" and "demo_b.cxx". The extensions are automatically found.
add_executable (helloDemo demo.cxx demo_b.cxx)

# Link the executable to the Hello library.
target_link_libraries (helloDemo Hello)

And here's the same example, showing the equivalent "C/Make" syntax you're used to:

Quote:

# -I$(HELLO_SOURCE_DIR)/Hello
include_directories (${HELLO_SOURCE_DIR}/Hello)

# -L$(HELLO_BINARY_DIR)/Hello
link_directories (${HELLO_BINARY_DIR}/Hello)

# -lhelloDemo -lHello
target_link_libraries (helloDemo Hello)
