Linking with cmake

Linking with cmake

Postby martinv » Mon May 30, 2011 5:58 pm

Dear LAPACK developers,

I compiled LAPACK 3.3.1 (on linux with gcc) and installed it in /home/martin/local/lapack. I would like to link a little test code against this library, but my cmake file always finds the lapack library which is installed in /usr/lib. The contents of my CMakeLists.txt is this:

Code: Select all
cmake_minimum_required(VERSION 2.8)

set(CMAKE_PREFIX_PATH "/home/martin/local/lapack/lib/cmake")

find_package(LAPACK REQUIRED)

  message("Found Lapack")
  add_executable(test lapack_test1.cpp)
  target_link_libraries(test ${LAPACK_LIBRARIES})
  message("Lapack link library is ${LAPACK_LIBRARIES}")

When I run cmake, the output is always the same:

Lapack link library is /usr/lib/;/usr/lib/

Could you please tell me what am I doing wrong? In case you don't use find_package(LAPACK), could you tell me what's the proper way to detect LAPACK compiled with cmake?

Thank you very much.

Best regards,

Martin Vymazal

If you use the CMAKE interface, before the generate, change the value of LAPACK_LIBRARIES
or set it directly on your command line.
