Building Libzip on MacOS with Cmake unable to find right package

Question

I'm building libzip [version 1.7.3]. The package uses CMake.

I do the following as initial setup:

wget -c https://github.com/nih-at/libzip/releases/download/v1.7.3/libzip-1.7.3.tar.gz
tar -zxf libzip-1.7.3.tar.gz
cd libzip-1.7.3
mkdir build && cd build

And then I run the following:

cmake -DCMAKE_INSTALL_PREFIX=/usr/local ..

However, Cmake seems unable to find libbz2 as I get the following among the list of messages:

-- Found BZip2: /Library/Frameworks/libbz2.framework (found version "1.0") 

I had previously installed libbz2 [and other dependencies like GnuTLS, Nettle, XZ, etc.] in /usr/local, and I can verify that libbz2.dylib is in /usr/local/lib.

I've tried setting CMAKE_PREFIX_PATH speifically to /usr/local. And I've also tinkered with FindBZip2.cmake, but I'm not a CMake expert so I didn't go beyond changing variable assignments [specifically forcing /usr/local to no avail].

It only works when I delete libbz2.framework, but that isn't a workable solution.

Is there way around this?

Answer 1

cmake -DCMAKE_IGNORE_PATH=/Library/Frameworks -DCMAKE_INSTALL_PREFIX=/usr/local ..

See cmake docs on CMAKE_IGNORE_PATH for more information.
