Makefile content is as follows

Three files in the same directory main.cpp Test1.cpp Test1.h Test2.cpp Test2.h

Final Result:

Due to the page layout makefile content please pay attention to re-use tab layout may not compile but

//=============================================================

The test environment for CMake is as follows

A main.cpp content can be compiled arbitrarily

A CMakeLists.txt

The contents are as follows:

PROJECT (Main) cmake_minimum_required (VERSION 2.6) aux_source_directory (. DIR_SRCS) add_executable (main ${dir_srcs})

The compilation results are as follows

CMake.--Configuring done--generating done--Build files has been written to:/HOME/A/DESKTOP/3

　　

make[100%] Building CXX object cmakefiles/main.dir/main.cpp.olinking CXX executable main[100%] Built target Main

//===================================================

Further down the root directory into main.cpp CMakeLists.txt

Place Test1.cpp Test1.h CMakeLists.txt in the new subdirectory of the SRC sub-directory

The root directory CMakeLists.txt content is as follows:

PROJECT (Main) cmake_minimum_required (VERSION 2.6) add_subdirectory (SRC) aux_source_directory (. DIR_SRCS) add_executable (main ${dir_srcs}  ) target_link_libraries (main Test)

The contents of the subdirectory CMakeLists.txt are as follows:

Aux_source_directory (. DIR_TEST1_SRCS) add_library (Test ${dir_test1_srcs})

The compilation is displayed as follows:
