change compression tool from gz to gzip

[pvonmoradi]

I'm on Xubuntu 18.04. Had to change these lines in CMakeCache.txt from gz to gzip

COMPRESS_EXECUTABLE:FILEPATH=/bin/gzip
MAN_COMPRESSION:STRING=gzip

[sergei-mironov]

Hi. CMakeCache.txt is an auto-generated file. I suspect there are some inconsistencies in your working environment (gzip package moved from /bin to somewhere like /usr/bin?). Consider re-generating it first by removing the whole build folder. Please suggest what changes should we do in CMakeLists.txt from the project root folder if the error remains.

In my setup, gz is an external tool (Gazebo), isn't the compression tool called gzip? I'm using Xubuntu 18, maybe distros have different names for same tools.

[sergei-mironov]

Maybe also a fork's issue? I use gzip, check here https://github.com/grwlf/xkb-switch/blob/master/CMakeLists.txt#L50

[sergei-mironov]

Oh, wait a minute.. https://github.com/grwlf/xkb-switch/blob/master/CMakeLists.txt#L52 stll mentions gz

[pvonmoradi]

@grwlf This time I used your latest master. https://github.com/grwlf/xkb-switch/blob/master/CMakeLists.txt#L41 and line 52 Yeah you already noted

[sergei-mironov]

Could you please check the latest master?

Builds fine 😉

Thanks!
