Installation Issues

[didahalpha]

Hello,
Some of us aren't as savy on how everything is to be installed, so I am running into an issue trying to get this installed, so I can eventually get Volk installed, where I will then install GnuRadio, on RHEL 7.
As for this one, can you please provide the instructions on how to compile this code?

I tried, within the build directory that I created in the unzipped folder of this download:

cmake3 ..
And got this:
-- Configuring done
-- Generating done
-- Build files have been written to: /opt/gnuradio-maint-3.8/cpu_features-main/build/googletest-download
[ 11%] Performing update step for 'googletest'
Current branch main is up to date.
[ 22%] No configure step for 'googletest'
[ 33%] No build step for 'googletest'
[ 44%] No install step for 'googletest'
[ 55%] No test step for 'googletest'
[ 66%] Completed 'googletest'
[100%] Built target googletest
-- Configuring done
-- Generating done
-- Build files have been written to: /opt/gnuradio-maint-3.8/cpu_features-main/build

Could you please tell me what I'm missing? :-)
Thanks a bunch,

Brad

@Mizux to update README.md with installation instructions.

On my way to fix the doc !

Otherwise you can look at our docker based CI to figure the needed cmds...
here you call cmake3 ... which only run the "configure" step (cmake is a GENERATOR build system), you also need the "build" step and the "install" step.

Basically

cpu_features/cmake/ci/docker/amd64/Dockerfile

Lines 27 to 29 in b04a9da

	RUN cmake -S. -Bbuild
	RUN cmake --build build --target all -v
	RUN cmake --build build --target install -v

note:on linux with the default generator (Makefile) will install everything in /usr/local BUT you can also use DESTDIR to avoid to pollute your host machine by using this cli instead.
cmake3 --build build --target install -v -- DESTDIR=install

then to consume it in a CMake project you can take a look at https://github.com/google/cpu_features/tree/main/cmake/ci/sample
