CMake installation and testing

上篇一文读懂CMakeWe've got the hang of itCMake的脚本编写.An installation, as the name suggests, is to install an application,For example, executables and dynamic libraries will be generated,Copy to the specified installation location.下面是install的基本语法.

安装

 install(TARGETS <target>... [...])
 install({
    FILES | PROGRAMS} <file>... [...])
 install(DIRECTORY <dir>... [...])
 install(SCRIPT <file> [...])
 install(CODE <code> [...])
 install(EXPORT <export-name> [...])

#DESTINATION 表示安装位置
#如果设置了CMAKE_INSTALL_PREFIX则表示在CMAKE_INSTALL_PREFIXbase location+DESTINATION 

#TARGETS Represents a list of target files 例如可执行文件,库文件
install(TARGETS MathFunctions DESTINATION lib)

#FILES 表示文件列表
install(FILES MathFunctions.h DESTINATION include)

设置完成之后执行cmake --install 目录(cmake的输出目录,Usually the current directory：build)

#执行Cmake
#cmake ../

#编译文件
#cmake --build .

#安装
#cmake --install .

#文件末尾添加
#设置安装目录,linux默认为/usr/local,windows默认为“C:\Program Files (x86)”
set(CMAKE_INSTALL_PREFIX "${PROJECT_BINARY_DIR}/install/")
#Print the current installation directory
install(CODE "message(\"CMAKE_INSTALL_PREFIX=${CMAKE_INSTALL_PREFIX}\")")
#安装指定文件
install(TARGETS hellow DESTINATION bin)

这样安装OK了,但是linux需要注意sosearch rules for,否则可能导致so找不到,Thus the program fails to run.

测试

cmake测试：As the name implies, it verifies the accuracy of the program through different parameters.（centos7没有找到ctest工具）.
