[cmake-developers] VS custom commands with VS variable containing space in executable path?

[Robert Goulet]

Hello,

I am trying to use a custom command to generate test certificate for a Universal Windows Platform app, and I can't find how to properly quote the executable paths from CMake. Here is how we add the custom command:

set(WIN64UWP_CERT_NAME "${PROJECT_NAME}_TemporaryKey")
add_custom_command(
OUTPUT "${PROJECT_BINARY_DIR}/${WIN64UWP_CERT_NAME}.pfx"
      COMMAND "$(WindowsSdkDir)/bin/x64/makecert.exe" -cy end -eku 1.3.6.1.5.5.7.3.3 -r -n "CN=${PRODUCT_COMPANY}" -sv ${RESOURCES_DIR}/${WIN64UWP_CERT_NAME}.pvk ${WIN64UWP_CERT_NAME}.cer
      COMMAND "$(WindowsSdkDir)/bin/x64/PVK2PFX.exe" -pvk ${RESOURCES_DIR}/${WIN64UWP_CERT_NAME}.pvk -spc ${WIN64UWP_CERT_NAME}.cer -pfx ${WIN64UWP_CERT_NAME}.pfx -f
            WORKING_DIRECTORY ${PROJECT_BINARY_DIR}
            COMMENT "Generating Test Certificate..."
)

Because $(WindowsSdkDir) points within C:\Program Files\... Visual Studio is unable to execute these commands since the .vcxproj does not contain quotes around the executable paths.

First I tried using \" around the command, but CMake refuses to escape quotes on the command with error "COMMAND may not contain literal quotes".

Then I tried XML escaped character " but then CMake translate the ; as it if was a different element of an array surrounding both sides with quotes.

Then I tried %22 but CMake outputs % as %% in the vcxproj file.

So how do we setup a custom command that uses a Visual Studio variable that requires to be quoted to preserve spaces?

Thanks!
