cmake添加版本号

vVersion.cmake文件内容如下：

#vversion.cmake

#vDateTime
string(TIMESTAMP vDateTime "%Y%m%d-%H%M%S")

#vProjectDir
execute_process(
  COMMAND basename ${CMAKE_CURRENT_SOURCE_DIR}
  WORKING_DIRECTORY ${CMAKE_CURRENT_SOURCE_DIR}
  OUTPUT_VARIABLE vProjectDir
  OUTPUT_STRIP_TRAILING_WHITESPACE
)

#vGitBranch
execute_process(
  COMMAND git rev-parse --abbrev-ref HEAD
  WORKING_DIRECTORY ${CMAKE_CURRENT_SOURCE_DIR}
  OUTPUT_VARIABLE vGitBranch
  OUTPUT_STRIP_TRAILING_WHITESPACE
)

#vGitCommit
execute_process(
  COMMAND git log -1 --pretty=format:%h
  WORKING_DIRECTORY ${CMAKE_CURRENT_SOURCE_DIR}
  OUTPUT_VARIABLE vGitCommit
  OUTPUT_STRIP_TRAILING_WHITESPACE
)

set(vFileName "${CMAKE_CURRENT_SOURCE_DIR}/vversion.h")

file(WRITE ${vFileName} "
#ifndef VVERSION_H
#define VVERSION_H
" )
file(APPEND ${vFileName} "const char* vversion="[vov]:${vDateTime}:${vProjectDir}:${vGitBranch}:${vGitCommit}";")
file(APPEND ${vFileName} "
#endif")

使用方法：在CMakeList.txt中添加：

include(vVersion.cmake)
