I want to use GMock in my project. First of all I compiled GMock and GTest. The sequence of my actions (I use Linux):
- git clone googlemock and googletest
- go to GIT/googletest/googlemock/build-aux/ directory run cmake .. and then make
- As the result I got: libgmock.a and libgmock_main.a
My project has the structure: build, inc, src and lib directories. In build directory I run cmake .. and make. In inc dir I placed all headers from GIT/googletest/googlemock/include/ and GIT/googletest/googletest/include/. In lib dir lays libgmock.a only. In src - sources of my project.
My CMakeLists.txt contains:
project(blockchain)
cmake_minimum_required(VERSION 2.6)
set(CMAKE_INSTALL_PREFIX ${CMAKE_CURRENT_SOURCE_DIR})
file(GLOB CPPS "*.cpp")
include_directories("../inc/")
link_directories("../lib/")
add_definitions(-Wall -O2 -std=c++11)
add_executable(${PROJECT_NAME} ${CPPS})
target_link_libraries(blockchain gmock)
install(TARGETS ${PROJECT_NAME} DESTINATION bin)
When I try to make my project (typing cmake .. && make in build dir) I get linking errors:

And a lot of others linking errors. What am I doing wrong?
