Is your feature request related to a problem? Please describe.

The directx-dxc package includes a command-line tool for compiling HLSL shaders, dxc, whose path is provided in the CMake variable DIRECTX_DXC_TOOL after the appropriate find_package call. Unfortunately, this executable does not appear to be executable by default on Linux.

/bin/sh: 1: /home/runner/work/project/project/vcpkg/installed/x64-linux/tools/directx-dxc/dxc: Permission denied

I added the following snippet to my project's CMake scripts to resolve the issue, verifying that the problem is just the missing executable bit.

 if(CMAKE_HOST_LINUX)
     execute_process(COMMAND "chmod" "+x" "${DIRECTX_DXC_TOOL}")
 endif()

Proposed solution

Set the executable bit on the dxc binary during the installation step of the port.

Adding an appropriate FILE_PERMISSIONS option to that command should resolve it, I believe.
