Question

我将CMake用于我的项目，并且依赖于多个不同的第三方库，它们本身都使用CMake。

其中许多在其主要CMake中提供Options，例如-

option(GLM_QUIET "No CMake Message" OFF)
option(BUILD_SHARED_LIBS "Build shared library" ON)
option(BUILD_STATIC_LIBS "Build static library" ON)
option(GLM_TEST_ENABLE_CXX_98 "Enable C++ 98" OFF)

option ( ASSIMP_BUILD_ASSIMP_TOOLS
  "If the supplementary tools for Assimp are built in addition to the library."
  ON
)
option ( ASSIMP_BUILD_SAMPLES
  "If the official samples are built as well (needs Glut)."
  OFF
)

默认情况下，我想将其中一些选项设置为与原始值不同。

在包含主要的CMake之前，我尝试过这样设置它们-

SET( ASSIMP_BUILD_ASSIMP_TOOLS OFF )

但随后我从CMake收到此错误：

CMake Warning (dev) at Thirdparty/glm/CMakeLists.txt:14 (option):
  Policy CMP0077 is not set: option() honors normal variables.  Run "cmake
  --help-policy CMP0077" for policy details.  Use the cmake_policy command to
  set the policy and suppress this warning.

  For compatibility with older versions of CMake, option is clearing the
  normal variable 'ASSIMP_BUILD_ASSIMP_TOOLS '.
This warning is for project developers.  Use -Wno-dev to suppress it.

如果我尝试这样做-

OPTION( ASSIMP_BUILD_ASSIMP_TOOLS OFF )

它只是悄悄地忽略了它。

解决这个问题的正确方法是什么？

设置第三方模块的默认选项值
