-------------------------------------+-------------------------------------
On my system, I currently have:
{{{
pkg-config --modversion vulkan
1.3.239
}}}
which doesn't meet the minimum requirements in `configure` of 1.3.255
(i.e. my header version is 239):
{{{
if enabled vulkan; then
check_pkg_config_header_only vulkan "vulkan >= 1.3.255"
"vulkan/vulkan.h" "defined VK_VERSION_1_3" ||
check_cpp_condition vulkan "vulkan/vulkan.h"
"defined(VK_VERSION_1_4) || (defined(VK_VERSION_1_3) && VK_HEADER_VERSION
>= 255)"
}}}
Unsuprisingly, the build fails on:
{{{

}}}
but this shouldn't have been attempted in the first place.
Moreover, passing `--disable-vulkan` doesn't avoid this issue either as it
will still try to build the vulkan hwaccels + filters etc.
