Summary
WiredTiger does not compile with the following flags set together:

• ENABLE_STRICT=1
• CMAKE_BUILD_TYPE=Release

Motivation

• Does this affect any team outside of WT?
  Anyone who tries to compile with those flags

• How likely is it that this use case or problem will occur?
  Every time we use those flags together

• If the problem does occur, what are the consequences and how severe are they?
  WiredTiger does not compile

• Is this issue urgent?
  I am not sure if those flags are expected to be incompatible.

Acceptance Criteria (Definition of Done)
If those flags should work together, WiredTiger should compile with the following commands:

mkdir build
cd build
cmake -DENABLE_STRICT=1 -DCMAKE_BUILD_TYPE=Release -G Ninja ../.
ninja

The current output is:

../ext/test/fail_fs/fail_fs.c: In function 'fail_fs_allocate_lock':
../ext/test/fail_fs/fail_fs.c:116:41: error: unused parameter 'lockp' [-Werror=unused-parameter]
 fail_fs_allocate_lock(pthread_rwlock_t *lockp)

Note: If RelWithDebInfo is used for CMAKE_BUILD_TYPE, the same issue occurs.
