Hi!
I just find the solution. The problem was in order how libraries were
specified.
target_link_libraries(${lib_name}
general rt
general dl
general pthread
debug ${do_scoring_debug}
optimized ${do_scoring}
general ${spinx}
general ${cblas}
general ${atlas}
)

Hi All!
I have a problem with target_link_libraries. It can't link with
shared libraries not from directory listed in LD_LIBRARY_PATH.
1. When I try to link shared library with the full path obtained
from find_library, my library is passed to gcc without -l option
as ordinary object file.
What is the problem with linking the absolute path of the shared
library? This should just work
2. When I try to link by specifying short name "cblas" I've got
the error message:
Linking CXX shared library
../../sndcompare/amd64sse3/libsndcompared.so
/usr/bin/ld: cannot find -lcblas
collect2: ld returned 1 exit status
make[2]: *** [../../sndcompare/amd64sse3/libsndcompared.so] Error 1
make[1]: *** [CMakeFiles/sndcompare.dir/all] Error 2
make: *** [all] Error 2
*** Failed ***
This is because the linker does not know the directory where to search
for the library.
add_library(${lib_name} SHARED
${io_files}
${utils_files}
${tech_independ_files}
${other_files}
)
find_library(atlas
NAME atlas
PATHS
${CMAKE_CURRENT_SOURCE_DIR}/${CMAKE_SYSTEM_NAME}/atlas/${arch}/lib
DOC "Atlas library"
)
find_library(cblas
NAME cblas
PATHS
${CMAKE_CURRENT_SOURCE_DIR}/${CMAKE_SYSTEM_NAME}/atlas/${arch}/lib
DOC "Cblas library"
)
link_directories(
${CMAKE_CURRENT_SOURCE_DIR}/${CMAKE_SYSTEM_NAME}/atlas/${arch}/lib
${CMAKE_CURRENT_SOURCE_DIR}/../../Sphinx/sphinxbase/${CMAKE_SYSTEM_NAME}/${arch}/lib
)
link_directories is not needed at all here or should not be needed.
Just make sure to pass ${cblas} and ${atlas} to
target_link_libraries. If that produces errors please provide the
exact error message.
