Development / contributor build

[alippai]

I've tried to build turbodbc based on https://turbodbc.readthedocs.io/en/latest/pages/contributing.html#development-version in order to develop it (I've always did it using the web editor ¯_(ツ)_/¯).

A few issues I'm facing when trying to build it using conda:

1. Pybind11 download

wget -q https://github.com/pybind/pybind11/archive/v2.9.1.tar.gz
tar xvf v2.9.1.tar.gz

Likely a rename of the inner folder to pybind11 is missing
2. I get

CMake Warning (dev) at turbodbc-dev/share/cmake-3.22/Modules/FindPackageHandleStandardArgs.cmake:438 (message):
  The package name passed to `find_package_handle_standard_args` (PkgConfig)
  does not match the name of the calling package (Arrow).  This can lead to
  problems in calling code that expects `find_package` result variables
  (e.g., `_FOUND`) to follow a certain pattern.
Call Stack (most recent call first):
  turbodbc-dev/share/cmake-3.22/Modules/FindPkgConfig.cmake:99 (find_package_handle_standard_args)
  cmake_scripts/FindArrow.cmake:26 (include)
  cpp/turbodbc_arrow/CMakeLists.txt:12 (find_package)

3. I get warning:

CMake Warning (dev) at cpp/cpp_odbc/Test/CMakeLists.txt:9 (add_dependencies):
  Policy CMP0046 is not set: Error on non-existent dependency in
  add_dependencies.  Run "cmake --help-policy CMP0046" for policy details.
  Use the cmake_policy command to set the policy and suppress this warning.

  The dependency target "googletest_build" of target "cpp_odbc_test" does not
  exist.

4. I get several similar warnings:

CMake Warning at pybind11/tools/pybind11Tools.cmake:165 (add_library):
  Cannot generate a safe runtime search path for target
  turbodbc_arrow_support because files in some directories may conflict with
  libraries in implicit directories:

    runtime library [libodbc.so.2] in /usr/lib64 may be hidden by files in:
      miniconda3/envs/turbodbc-dev/lib

  Some of these libraries may not be found correctly.

5. linking fails with dozens of errors like this:

[ 32%] Linking CXX executable cpp_odbc_test
CMakeFiles/cpp_odbc_test.dir/cpp_odbc_test/level1_mock_api.cpp.o: In function `testing::internal::ExpectationBase::DescribeLocationTo(std::ostream*) const':
miniconda3/envs/turbodbc-dev/include/gmock/gmock-spec-builders.h:714: undefined reference to `testing::internal::FormatFileLocation(char const*, int)'

I assume I'm missing a build step running the (c)make for the google test or a similar issue.
