How do I make CMake look for a library in a specific directory?

Trying to install the Spenvis package and here is the error I get when running the script:

-- Boost version: 1.41.0
-- Found the following Boost libraries:
--   python
-- Configuring done
-- Generating done
-- Build files have been written to: Desktop/build
make[2]: *** No rule to make target `/usr/local/lib64/libpython2.6.so.1.0', needed by `source/libSpenvis.so'.  Stop.
make[1]: *** [source/CMakeFiles/Spenvis.dir/all] Error 2
make: *** [all] Error 2

      

        
        
        
      

    

It looks for libpython2.6.so.1.0 in / usr / local / lib 64, but the library itself is in / usr / lib 64.

I am not a superuser, so I cannot change / copy the library to the directory and cannot link to it. For reference, a python script is executed here, followed by the CMakeLists.txt file:

"""
Main launch script
"""
import os
import sys
import shutil
from subprocess import call

"""
Define path where to find python packages
"""
loc_dir=os.getcwd()
os.chdir("python_utilities")

#Spenvis csv
#############
os.chdir("spenvis_csv")
if not os.path.exists("build"):
    os.mkdir("build")

os.chdir("build")
call("cmake ../", shell=True)
call("make")
os.chdir(loc_dir)
os.chdir("python_utilities")
if not os.path.exists("lib"):
    os.mkdir("lib")

for file_name in os.listdir("spenvis_csv/build/source"):
    if file_name.find("libSpenvis.") !=-1:
        shutil.move("spenvis_csv/build/source/%s" %(file_name),"lib/Spenvis.so") 
os.chdir("..")

      

        
        
        
      

    

And CMakeLists.txt:

cmake_minimum_required(VERSION 2.8)

# Make sure the compiler can find include files
include_directories (${PYSPENVIS_SOURCE_DIR})


# get boost
set(Boost_USE_STATIC_LIBS   OFF)
#set(Boost_USE_MULTIEADED ON)
find_package(Boost COMPONENTS
                python
             REQUIRED)
include_directories(${Boost_INCLUDE_DIRS})
link_directories(${Boost_LIBRARY_DIRS})

# get python
include(FindPythonLibs)

set(PythonLibs_USE_STATIC_LIBS   OFF)
find_package(PythonInterp)
find_package(PythonLibs)
include_directories(${PYTHON_INCLUDE_DIRS})
link_directories(${PYTHON_LIBRARIES})

add_library(Spenvis  SHARED pySpenvisCSV.cc SpenvisCSV.cc SpenvisCSVCollection.cc)
TARGET_LINK_LIBRARIES(Spenvis ${Boost_LIBRARIES} ${PYTHON_LIBRARIES})

      

        
        
        
      

    

Taking the advice, I ran the following command in the directory containing the CMakeLists.txt file:

cmake -DPYTHON_LIBRARY='/usr/lib64/libpython2.6.so.1.0'

      

        
        
        
      

    

It happened:

Boost  found.
Found Boost components:
   python
-- Found PythonLibs: /usr/lib64/libpython2.6.so.1.0 (found version "2.7.1") 
-- Found PythonLibs: /usr/lib64/libpython2.6.so.1.0 (found suitable version "2.7.1", minimum required is "2.6") 
-- Configuring done
-- Generating done
-- Build files have been written to: blahblahblah

      

        
        
        
      

    

Returning to running the install.py program now returns:

-- Boost version: 1.41.0
-- Found the following Boost libraries:
--   python
-- Found PythonLibs: /usr/local/lib64/libpython2.6.so.1.0 (found version "2.6.6")

So the same error is returned, only now it claims to find python libraries. It's strange, however, that the python libraries they find don't exist, that is, there is no libpython2.6.so.1.0 in / usr / local / lib64, but instead it is in / USR / lib 64.

In CMakeCache.txt, the lines related to the required library are as follows:

//No help, variable specified on the command line.
PYTHON_LIBRARIES:UNINITIALIZED=/usr/lib64/libpython2.6.so.1.0

//Path to a library.
