Question

我试图制作运行CMake的PowerShell脚本。这是我的示例代码（最后展示$CMAKE_OPTIONS = @{ "DBUILD_opencv_java:BOOL" = "OFF" "DBUILD_opencv_python:BOOL" = "OFF" "DBUILD_opencv_python2:BOOL" = "OFF" "DBUILD_opencv_python3:BOOL" = "OFF" "DBUILD_TESTS:BOOL" = "OFF" "DBUILD_PERF_TESTS:BOOL" = "OFF" "DBUILD_DOCS:BOOL" = "OFF" "DBUILD_EXAMPLES:BOOL" = "OFF" "DINSTALL_CREATE_DISTRIB:BOOL" = "ON" } # ... add something from user input cmake -G $CMAKE_CONFIG_GENERATOR -DOPENCV_EXTRA_MODULES_PATH=$myRepo/opencv_contrib/modules -DCMAKE_INSTALL_PREFIX=$myRepo/install/$REPO_SOURCE $myRepo/$REPO_SOURCE @CMAKE_OPTIONS）：

foo = bar

但是我收到了一个错误：

命令行参数中的解析错误：-DBUILD_opencv_python：BOOL：OFF
  应该是：VAR：type = value
  CMake错误：未提供cmake脚本。
  CMake错误：处理参数的问题。中止。

似乎不是写论据foo:bar而是&cmake -p "myargs" $CMAKE_OPTIONS_STRING。如何在调用外部程序时正确地展开参数？或者我是否必须使用字符串连接和client = Mysql2::Client.new(:host => host, :username => username, :password => password, :database => database)的旧方法？

对于外部程序，使用数组，而不是哈希表：

$CMAKE_OPTIONS = @(
  "-DBUILD_opencv_java:BOOL=OFF",
  "-DBUILD_opencv_python:BOOL=OFF",
  "-DBUILD_opencv_python2:BOOL=OFF",
  "-DBUILD_opencv_python3:BOOL=OFF",
  "-DBUILD_TESTS:BOOL=OFF",
  "-DBUILD_PERF_TESTS:BOOL=OFF",
  "-DBUILD_DOCS:BOOL=OFF",
  "-DBUILD_EXAMPLES:BOOL=OFF",
  "-DINSTALL_CREATE_DISTRIB:BOOL=ON"
)

cmake ... @CMAKE_OPTIONS

为外部程序提供参数
