[cmake] make install in cmake under windows is installed to the specified directory usage

Problem : Most of the tutorials are under uinx, and the cmake file INSTALL is installed. But because the default path prefix is ​​also Unix-like.

INSTALL(FILES COPYRIGHT README DESTINATION share/doc/cmake/)

DESTINATION, the path to the installation file is actually /usr/local/share/doc/cmake/

But there is no such path under windows. So modify the default path prefix.

solve:

Common steps (under linux):

mkdir build && cd build
cmake ..
make
make install

1. The initial file tree

PS D:\Code\cmaketest\cmake_test03> tree /F
卷 Data 的文件夹 PATH 列表
卷序列号为 6E99-8D8D
D:.
│  CMakeLists.txt
│  COPYRIGHT
│  README

│
├─build
├─doc
│      hello.txt
│
└─src
        CMakeLists.txt
        main.cpp

2. Switch to cd .\build\

PS D:\Code\cmaketest\cmake_test03> cd .\build\

3. cmake input cmake -S ../ -B ./ -G "MinGW Makefiles"

PS D:\Code\cmaketest\cmake_test03\build> cmake -S ../ -B ./ -G "MinGW Makefiles"

4.cmake modifies the default installation path prefix . critical step

输入cmake -DCMAKE_INSTALL_PREFIX=D:\cmakeinstalltest\ -DCMAKE_C_COMPILER=gcc -DCMAKE_CXX_COMPILER=g++ -G"MinGW Makefiles" ../
