c++ - 使用 CMake 构建时缺少依赖项

Question

我正在尝试构建 Polycode使用CMake的代码。我按照 Build.md 中的说明进行操作文件，但出现以下错误:

$ cmake -G "Visual Studio 10" ..
No POLYCODE_RELEASE_DIR specified, to C:/Development/Polycode/Release/Windows
DEBUG CMAKE_PREFIX_PATH=C:/Development/Polycode/Release/Windows/Framework/Core/Dependencies;C:/Development/Polycode/Release/Windows/Framework/Modules/Dependencies;C:/Development/Polycode/Release/Windows/Framework/Tools/Dependencies
CMake Error at c:/Program Files (x86)/CMake 2.8/share/cmake-2.8/Modules/FindPackageHandleStandardArgs.cmake:97 (message):
  Could NOT find ZLIB (missing: ZLIB_LIBRARY ZLIB_INCLUDE_DIR)
Call Stack (most recent call first):
  c:/Program Files (x86)/CMake 2.8/share/cmake-2.8/Modules/FindPackageHandleStandardArgs.cmake:291 (_FPHSA_FAILURE_MESSAGE)
  c:/Program Files (x86)/CMake 2.8/share/cmake-2.8/Modules/FindZLIB.cmake:85 (FIND_PACKAGE_HANDLE_STANDARD_ARGS)
  CMake/PolycodeIncludes.cmake:14 (FIND_PACKAGE)
  Core/Contents/CMakeLists.txt:2 (INCLUDE)


-- Configuring incomplete, errors occurred!

我看到它需要 ZLIB，但我不知道如何处理。它不应该自动下载依赖项吗？我当然可以找到 ZLIB 并下载它，但我真的不想对它可能需要的每个库都这样做。有什么方便的方法可以解决这个问题吗？

Answer 1

这是一个两步构建过程。首先，您需要构建依赖项:

cd Dependencies  # <---- this will run the next steps in the Dependencies subdirectory of your Polycode repo
mkdir Build
cd Build
cmake -G "Visual Studio 10" ..

此步骤应安装所需的库。只有这样，您才能继续构建 Polycode 本身

# <---- this build step is run inside your Polycode root directory
mkdir Build
cd Build
cmake -G "Visual Studio 10" ..
