Hello cmake-experts,
I am working on a project that uses a third-party library delivered in
binary form (TeamSpeak 3 SDK). My project is supposed to build on Win,
Linux, and OSX, so I decided to use cmake as a build tool. I have
started work on a Findts3sdk.cmake (find_package() in module mode) to
let cmake detect the library in the CMAKE_PREFIX_PATH on any of my
machines - file attached at the end of this mail.
My (current) problem is that a call to find_path() in my
Findts3sdk.cmake will not pick up the bin directory containing the
libraries, while another call did work to find the include directory.
WORKS (ts3sdk_INCLUDE_DIR == /path/to/ts3_sdk_3.0.3/include):
> find_path(ts3sdk_INCLUDE_DIR NAMES clientlib.h HINTS
> ${CMAKE_PREFIX_PATH}/include)
BROKEN (ts3sdk_LIBRARY_DIR == ts3sdk_LIBRARY_DIR-NOTFOUND):
> find_path(ts3sdk_LIBRARY_DIR NAMES libts3client_mac.dylib HINTS
> ${CMAKE_PREFIX_PATH}/bin)
I deduce from this that CMAKE_PREFIX_PATH is set correctly. I have tried
the broken command with other names of the library file as well
(ts3client_mac, libts3client_mac, libts3client_mac.dylib,
ts3client_mac.dylib).
What do I have to fix to make find_path() pick up the library file?
I am currently on a Mac, using cmake 3.1.3 installed from MacPorts.
cmake is called with -DCMAKE_PREFIX_PATH="/path/to/ts3_sdk_3.0.3".
The layout of the library delivery is as follows:
> ts3_sdk_3.0.3
> ├── bin
> │ ├── libts3client_linux_amd64.so
> │ ├── libts3client_linux_x86.so

My current Findts3sdk.conf looks as follows:
> # Find the INCLULDE and LIBRARY path
> find_path(ts3sdk_INCLUDE_DIR NAMES clientlib.h HINTS
> ${CMAKE_PREFIX_PATH}/include)
