Adding a library
├── CMakeLists.txt ├── MathFunctions │ ├── CMakeLists.txt │ ├── MathFunctions.h │ └── mysqrt.cxx └── tutorial.cxx
In MathFunctions/CMakeLists.txt
add_library(MathFunctions mysqrt.cxx)
add_library: create a library, static or dynamic library.
In ./CMakeList.txt
cmake_minimum_required (VERSION 2.6) project (Tutorial) # add the binary tree to the search path for include files # so that we will find TutorialConfig.h include_directories ("${PROJECT_BINARY_DIR}") include_directories ("${PROJECT_SOURCE_DIR}/MathFunctions") add_subdirectory (MathFunctions) # add the executable add_executable (Tutorial tutorial.cxx) target_link_libraries (Tutorial MathFunctions)
include_directories: to find the header files
add_executable: to create executable
target_link_libraries: add the library to the executable
