Little Problem to connect Compile Instruction

[Mungo1981]

Dear Community,
I have a little Problem to connect Compiler Instructions for g++ on Linux Ubuntu Mint.
The Problem is that I can combine not following instructions.:
I Have to compile wx-widgets per:
g++ test.cpp `wx-config --libs --cxxflags` -std=c++11 -o Test2
And to compile libpq4 per:
g++ test.cpp -lpqxx -lpq -o Test2
together.
And I can not imagine me how this should be written.
My version are:
g++ test.cpp `wx-config --libs --cxxflags` -std=c++11 -lpqxx -lpq -o Test2
And this wouldn't work.
Anybody a Imagination how to solve this.???

P.S.: I knew is a little bit tricky question. But I'm a crazy person.

Did you look at the output after you ran the command? What did it say?
