CMake找不到glog

Question

CMAKE_MINIMUM_REQUIRED(VERSION 2.8.7 FATAL_ERROR)

INCLUDE(FindPackageHandleStandardArgs)

FIND_LIBRARY(GLOG_LIBRARY glog)
FIND_PATH(GLOG_INCLUDE_DIR "glog/logging.h")

SET(GLOG_LIBRARIES ${GLOG_LIBRARY})

FIND_PACKAGE_HANDLE_STANDARD_ARGS(
  Glog
  REQUIRED_ARGS GLOG_INCLUDE_DIR GLOG_LIBRARY)

这是cmake文件。我在/apps/glog中安装了google glog 0.3.4。为什么在编译这个文件时，仍然会出现以下错误？我检查过了，glog/logging.h在0.3.4/include/glog/下。

CMake Error at cmake/FindGlog.cmake:77 (MESSAGE):
  Failed to find glog - Could not find glog include directory, set
  GLOG_INCLUDE_DIR to directory containing glog/logging.h
Call Stack (most recent call first):
  cmake/FindGlog.cmake:103 (GLOG_REPORT_NOT_FOUND)
  CMakeLists.txt:27 (FIND_PACKAGE)

Answer 1

Glog现在(在这个问题被问到最多四年后)支持CMake！这里有非常好的文档：https://github.com/google/glog#cmake

但这是你应该做的要点：

cmake_minimum_required (VERSION 3.0.2)
project(myproj VERSION 1.0)

find_package(glog 0.6.0 REQUIRED)

add_executable(myapp main.cpp)
target_link_libraries(myapp PRIVATE glog::glog)

就像任何其他行为良好的、支持CMake的库一样！

截至2017年11月18日，官方glog暂不支持CMake。

GitHub user sergiud在分支中添加了CMake支持。请参阅https://github.com/google/glog/issues/4中的讨论。
