Cannot build the lib due to CMake Export pb

[cmassaloux]

Hi !
One year ago, I have built the lib without problem
But today, CMake complains about Export problem.
I guess it's a new version of CMake that brings this issue.

My environment:
Linux Ubuntu 20.04.4 LTS with gcc 9.4.0 + cmake 3.16.3
I also face the same issue with Ret Had Enterprise 8.7 + gcc 8.5.0 + cmake 3.18.2 or 3.20.2 (both tested)

The error message is:
CMake Error: install(EXPORT "cpp_redis" ...) includes target "cpp_redis" which requires target "tacopie" that is not in any export set.

I tried to figure things out, but I'm really not good at understanding CMake configuration files. Sorry...

Here is the full log:
$ cmake .. -DCMAKE_BUILD_TYPE=Release

-- Check for working CXX compiler: /usr/bin/c++

CMake Warning (dev) at tacopie/CMakeLists.txt:41 (project):
Policy CMP0048 is not set: project() command manages VERSION variables.
Run "cmake --help-policy CMP0048" for policy details. Use the cmake_policy
command to set the policy and suppress this warning.

The following variable(s) would be set to empty:

PROJECT_VERSION
PROJECT_VERSION_MAJOR
PROJECT_VERSION_MINOR
PROJECT_VERSION_PATCH

This warning is for project developers. Use -Wno-dev to suppress it.

Hoping that you could find out what's wrong.
By the way, your lib is great work, many thanks for having provided to the community.
