Hi I just started testing 3.5.0-rc1 on Linux and I noticed regression in Makefile generation time. I checked 3.5.0rc1, 3.4.3 and 3.2.2 versions, and the results are as follows:
64bit cmake 3.5.0-rc1 Makefile Generation 1. Run real 2m36.457s user 2m32.008s sys 0m3.184s 2. Run real 2m36.764s user 2m31.672s sys 0m3.296s 64bit cmake 3.4.3 Makefile Generation 1. Run real 1m29.679s user 1m24.696s sys 0m2.920s 2. Run real 1m28.266s user 1m24.220s sys 0m2.976s 64bit cmake 3.2.2 Makefile Generation 1. Run real 1m57.894s user 1m54.160s sys 0m2.320s 2. Run real 1m57.083s user 1m53.076s sys 0m2.304s Is it known issue? Do you have suspects what could cause this regression?
