CMake find_package（）不尊重CMAKE_MODULE_PATH

我在CMake中检测到软件包（glfw）时遇到问题。由于没有root权限，我无法在标准位置安装该库，因此我将其安装在.local：

$ ls ~/.local/lib/cmake/glfw3/glfw3Config.cmake
/home/emil/.local/lib/cmake/glfw3/glfw3Config.cmake

我的CMakeLists.txt组成

cmake_minimum_required(VERSION 3.10.0)
project(test VERSION 1.0 LANGUAGES C CXX)
set(CMAKE_MODULE_PATH ${CMAKE_MODULE_PATH} "$ENV{HOME}/.local")
message("CMAKE_MODULE_PATH: ${CMAKE_MODULE_PATH}")
find_package(glfw3 3.2 REQUIRED)

我使用以下标志执行该命令以确保搜索目录输出：

$ cmake -DCMAKE_FIND_DEBUG_MODE=ON ..

输出：

CMake Error at CMakeLists.txt:13 (find_package):
  By not providing "Findglfw3.cmake" in CMAKE_MODULE_PATH this project has
  asked CMake to find a package configuration file provided by "glfw3", but
  CMake did not find one.

因此，CMake似乎在很多地方（包括我的主目录）进行搜索，但不在~/.local。我实际上不确定为什么。我认为CMAKE_MODULE_PATH应该添加搜索目录。在我的另一台计算机上，它看起来在那里并在运行相同脚本时找到它。错误的机器运行Ubuntu MATE 18.04，并且正在运行一个Ubuntu 18.04。

CMake版本如下。

$ cmake --version
cmake version 3.10.2

我知道我可以将文件移到主目录，但是我不想这样做。
