Linking issue on MacOS Catalina (using XCode)

I installed Crypto++ from source as follows:

   1. git clone https://github.com/weidai11/cryptopp.git
   2. cd cryptopp
   3. Uncommented the CXX flag line in GNUmakefile that adds 
   "-stdlib=libc++" because I am using XCode. 
   4. make -j 8 (8 = value of $(nproc) on my machine if it were linux)
   5. sudo make install

The make and install complete without errors. I confirmed that 
/usr/local/lib contains libcryptopp.a.

When I try to use libcryptopp in a project (in a different directory from 
the cryptopp install), clang (Apple Clang 12.0.0) can't find it. I get the 
following error message:

+ LD     lib/crypto_bench
ld: library not found for -l:libcryptopp.a
clang: *error: *linker command failed with exit code 1 (use -v to see 
invocation)

This is the output of gcc --version (gcc is linked to clang but not 
directly used):

Configured with: --prefix=/Applications/Xcode.app/Contents/Developer/usr 
--with-gxx-include-dir=/Library/Developer/CommandLineTools/SDKs/MacOSX.sdk/usr/include/c++/4.2.1

Apple clang version 12.0.0 (clang-1200.0.32.29)

Target: x86_64-apple-darwin19.6.0

Thread model: posix

InstalledDir: 
/Applications/Xcode.app/Contents/Developer/Toolchains/XcodeDefault.xctoolchain/usr/bin
I also tried updating my PATH variable in bash_profile with the location of 
libcryptopp as follows, then source'd bash_profile again:

export PATH="/usr/local/lib:$PATH"
However, this resulted in the same error as before when I tried to compile 
the project. I've spent several hours googling and haven't been able to 
find a fix, and I'm wary of manually symlinking the file because it can 
break other installs on my laptop. Any help with fixing this issue would be 
much appreciated.
