Multidimensional B-Spline Interpolation of Data on a Regular Grid created by Jacob Williams. Look here for original and description. This fork provides CMake installation of subroutines (no object-oriented interface). Useful when you have old compiler (Gfortran < 4.9).
The library is installed in user-space (${HOME}/lib/bspline) and (${HOME}/include/bspline) by default.
mkdir build; cd build
cmake .. -DCMAKE_INSTALL_PREFIX=$HOME
make
make install
Verify that the library and include files can be found:
export PKG_CONFIG_PATH=${HOME}/lib/pkgconfig
pkg-config --cflags --libs libbspline
Expect output similar to:
-I/home/advsim/include/bspline -L/home/advsim/lib/bspline -lbspline
