[regression][configure] commit 33ac97cd cause build problem

[Bin-CI]

we build this repo without wayland support and without BUILD_TOOLS=OFF before But now we need to add BUILD_TOOLS=OFF for the build, so it is the configure problem

User Specified Option	Requirements Met (e.g. deps)?	Feature Result	Configure Result
BUILD_TOOLS=OFF	Yes	Disabled	Success
BUILD_TOOLS=OFF	No	Disabled	Success
BUILD_TOOLS=ON	Yes	Enabled	Success
BUILD_TOOLS=ON	No	Error	Error
Unspecified	Yes	Enabled	Success
Unspecified	No	Disabled	Success

The table (above) are the expected results. But the last use-case does not work.
The user should not be forced to disable an optional feature because they don’t have or want its dependencies installed.
The configure should automatically turn on/off optional features if the user does not specify it explicitly.
The only time configure should error is if the user explicitly enables an optional feature but has not satisfied the requirements (e.g. dependencies).

@Bin-CI , maybe providing a configuration comandline and output is helpful

cmake -DCMAKE_INSTALL_PREFIX="/opt/media/install" -DCMAKE_INSTALL_LIBDIR="/opt/media/install/lib"

@Bin-CI Are you asking for an explicit waylaid enable/disable configuration for tools? Do you want the same for X11?

[Bin-CI]

like the configure table :
as build option without any configure, so the default behavior should be execute without any block
you can dump the configure result like wayland-protocols not found without build tools,
not told user need add build option to finish the configure step
