[CMake] Use of -J option with cmake generated makefiles

[Yann Renard]

Dear cmake users,

I would like to use the -j option of make in order to speed up
compilation process using 2 jobs better than 1 (hyperthreading
processor). Problem is the console output is totally messed up
(percentages, name of the file to compile/link etc...). Would you share
a tip to make this work better ?

Thank you,

best regards
Yann Renard
