A good practice is to make out-of-source builds, because you can easily find
out what files have been produced by the build system, and you can also work
with differently configured versions of the library at the same time.
For example, you can create a debug build compiled with gcc, and a fast build
compiled with Intel compilers:
```
./autogen.sh
mkdir -p _build_gcc_debug/_install
cd _build_gcc_debug
../configure --enable-debug --prefix=$PWD/_install
make -j
make -j check
cd ..
mkdir -p _build_intel_fast/_install
cd _build_intel_fast
../configure --prefix=$PWD/_install --enable-hpc --with-icc --with-ifort
make -j
make -j check
```
