anyway to link my local software

[YancyW]

I am using deepin system, always have problems for installing cepcsoft.
Fox example, when compiling gcc4.9.4, which is downloaded by "cepcenv install 0.1.0", there are many errors because some of gcc grammars were changed. although I tried to fix them, but there are so many..

But if I install gcc by myself with "sudo apt install gcc", it works.
The same problem also happens for QT.

Thus, is there any way that I can link my local software into cepcenv, without using cepc's default software?
