Could not find a package configuration file provided by "Ceres" with any of the following names:

This error usually occurs when you are trying to build a project that depends on the Ceres solver library, but the library is not found in the system.

To solve this issue, you need to install Ceres solver and make sure it is properly installed and configured. Here are the general steps to install Ceres solver on Ubuntu:

1. Install the necessary dependencies:

sudo apt-get install cmake libgoogle-glog-dev libgflags-dev libatlas-base-dev libsuitesparse-dev

2. Clone the Ceres solver repository:

git clone https://ceres-solver.googlesource.com/ceres-solver

3. Create a build directory inside the cloned repository:

cd ceres-solver
mkdir build
cd build

4. Configure CMake to build the library:

cmake ..

5. Build the library:

make -j8

6. Install the library:

sudo make install

After installation, make sure that the Ceres package is properly configured. You can do this by running the following command:

pkg-config --cflags --libs ceres

This should output the necessary compiler and linker flags for using Ceres in your project.
